<h2 class=”wp-block-heading” id=”h-hbo-harry-potter-series-casts-mcgonagall-hagrid-and-more”>HBO ‘Harry Potter’ series casts McGonagall, Hagrid, and more</h2>
<p id=”par-2_80″>Perhaps the most buzzworthy casting is <a href=”https://www.cheatsheet.com/entertainment/casting-john-lithgow-dumbledore-new-harry-potter-series.html/”>John Lithgow stepping into the role of Albus Dumbledore</a>. At 79, Lithgow brings a towering physical presence (6’4″) and a storied resume that includes <em>The Crown</em>, <em>Dexter</em>, and two Academy Award nominations. He follows in the footsteps of Richard Harris and Michael Gambon, who brought distinct interpretations of the beloved headmaster. While Harris exuded gentle wisdom and Gambon a more commanding authority,<a href=”https://www.cheatsheet.com/news/5-best-john-lithgow-movies.html/”> Lithgow’s theatrical gravitas and versatility</a> could offer a balanced fusion of both.</p>
<p id=”par-3_73″>Paapa Essiedu takes on the challenging mantle of Severus Snape, originally played by the late Alan Rickman, whose nuanced portrayal became iconic. At just 34, Essiedu is significantly younger than Rickman was at the time of his casting (55), suggesting the series might explore more of Snape’s formative years. Known for standout roles in <em>I May Destroy You</em> and <em>Gangs of London</em>, Essiedu brings a fresh, emotionally intense dynamic to the enigmatic professor.</p>
<p id=”par-4_45″>Janet McTeer, a towering 6’1” Oscar-nominated actor, will portray Professor McGonagall. While Maggie Smith’s performance was often described as the perfect mix of sternness and heart, McTeer’s Royal Shakespeare Company roots and dramatic depth (<a href=”https://www.cheatsheet.com/news/ozark-season-3-why-navarro-stopped-seeing-value-in-helen-pierce.html/”>seen in <em>Ozark</em></a> and <em>Albert Nobbs</em>) make her a promising successor.</p>
<p id=”par-5_55″>Meanwhile, Nick Frost—beloved for his comedic roles in <em>Shaun of the Dead</em> and <em>Hot Fuzz</em>—steps into the giant boots of Rubeus Hagrid, following the late Robbie Coltrane. At 5’8″, Frost is notably shorter than Coltrane (6’1″), but fans can expect HBO’s visual effects to work their magic once again to portray the half-giant’s massive stature.</p>
<p id=”par-6_60″>New additions to the cast include Luke Thallon as the jittery Professor Quirrell and Paul Whitehouse, a veteran British comedian, as the cantankerous caretaker Argus Filch. These roles were previously portrayed by Ian Hart and David Bradley, respectively. Thallon brings strong stage credentials, while Whitehouse’s blend of dry wit and sharp timing may offer a more humorous take on Filch.</p>

<p id=”par-7_53″>The series seems to be leaning into a mix of prestige and reinvention, with casting choices that reflect a broader age range, fresh cultural backgrounds, and strong theatrical pedigrees. HBO’s approach may not simply recreate the magic of the original films—it appears poised to reinterpret it with bold, character-driven storytelling over multiple seasons.</p>
<p id=”par-8_38″>As production begins, expect endless debates, breakdowns, and excitement over how <a href=”https://www.cheatsheet.com/news/daniel-radcliffe-1-wish-new-harry-potter-cast.html/”>these new actors will embody the characters</a> we’ve all grown up with. One thing’s for certain: Hogwarts is getting ready for a whole new generation of storytelling.</p>
